模拟 HttpClient.execute 问题:Mockito [英] Mocking HttpClient.execute issues: Mockito

问题描述

我正在尝试测试此方法.

I am trying to test this method.

@Override
public JSON connectResource() throws IOException {
    //get the location and credentials for the certificates
    System.setProperty("javax.net.ssl.trustStore", "C:/Program Files/Java/jdk1.7.0_40/jre/lib/security/cacerts");
    System.setProperty("javax.net.ssl.trustStorePassword", "changeit");
    HttpRequest httpRequest = new HttpGet(url);
    System.out.println("hello");
    httpRequest.addHeader("Accept", "application/json");
    HttpResponse response = httpClient.execute((HttpUriRequest) httpRequest);
    System.out.println("hello1");
    HttpEntity httpEntity = response.getEntity();
    String data = this.getData(httpEntity);
    return  JSONSerializer.toJSON(data.toString());
}

我的设置方法是:

@Before
public void setUp() throws Exception{
    mockHttpClient = mock(DefaultHttpClient.class);
    mockHttpRequest = mock(HttpUriRequest.class);
    mockHttpResponse = mock(BasicHttpResponse.class);
    mockHttpEntity = mock(HttpEntity.class);
    mockInputStream = mock(InputStream.class);
    mockInputStreamReader = mock(InputStreamReader.class);
    mockBufferedReader = mock(BufferedReader.class);
    mockHttpGet = mock(HttpGet.class);
    mockHttpRequestBase = mock(HttpRequestBase.class);
    //when(mockHttpClient.execute(Mockito.isA(HttpUriRequest.class))).thenReturn(mockHttpResponse);
    //when(mockHttpClient.execute(mockHttpRequest)).thenReturn(mockHttpResponse);
    //when(mockHttpClient.execute(mockHttpRequestBase)).thenReturn(mockHttpResponse);
    //when(mockHttpClient.execute(mockHttpGet)).thenReturn(mockHttpResponse);

    when(mockHttpResponse.getEntity()).thenReturn(mockHttpEntity);
    when(mockHttpEntity.getContent()).thenReturn(mockInputStream);
    PowerMockito.whenNew(InputStreamReader.class)
            .withArguments(mockInputStream).thenReturn(mockInputStreamReader);
    PowerMockito.whenNew(BufferedReader.class)
            .withArguments(mockInputStreamReader).thenReturn(mockBufferedReader);
    PowerMockito.when(mockBufferedReader.readLine())
            .thenReturn(JSON_STRING)
            .thenReturn(null);
    PowerMockito.whenNew(HttpGet.class).withArguments(VALID_URL)
            .thenReturn(mockHttpGet);
}

我的测试用例是:

 @Test
    public void testConnectResource() throws IOException {
        when(mockHttpClient.execute(mockHttpGet)).thenReturn(mockHttpResponse);
        HttpConnectGithub connHandle = new HttpConnectGithub(VALID_URL);
        JSON jsonObject = connHandle.connectResource();
        System.out.println(jsonObject);
        //assertThat(jsonObject, instanceOf(JSON.class));
    }

然而，执行在

HttpResponse response = httpClient.execute((HttpUriRequest) httpRequest);

您可以在我的设置方法的评论中看到我尝试的所有内容.有没有人发现任何问题?我调试了我的测试用例，所有模拟对象都已正确初始化.我尝试过交换 HttpUriRequest 和 HttpRequest、HttpResponse 和 BasicHttpResponse 等，但运气不佳.请指导如何解决这个问题.

you can see all that I tried in the comments of my set up method. Does anyone find an issue with anything? I debugged through my test case and all mock objects are properly initialized. I have tried exchanging HttpUriRequest and HttpRequest, HttpResponse and BasicHttpResponse etc but without much luck. Please guide on how to tackle this issue.

推荐答案

问题在于 mockHttpClient.由于某种原因，它无法自动模拟它.解决方法是通过某种方法(在我的情况下是构造函数)将 httpclient 作为参数传递

The problem is with mockHttpClient. It is not able to mock it automatically for some reason. The fix is to pass httpclient as a parameter through some method (constructor in my case)
